On 10/08/2009 my 209 hyundai sonata went into an unintended acceleration. As soon as I put the car into drive it began to accelerate. The brakes did not work and I was able to shift into neutral. I was on a narrow dirt road with little limited options as to where to steer the vehicle. I missed a boulder, garage, and tree before hitting the side of a house. The ambulance was called and I was transported to the local emergency room. I had a concussion, fractured knee along with a number of bruises and abrasions. The emts told me how lucky if was since the air bags did not deploy.. An internet search, including your website, notes these problems going back several years. Toyota had the same problem and did a recall. My injuries will exceed the limit of my insurance and I will have to purchase a car. I know how lucky I was to walk away. I am sure others had more serious injuries and higher expenses. What does it take to force hyundai to do the right thing?

Upon accelerating up an entrance ramp to the highway, car accelerated at an unreasonable rate of speed tried using brakes, but they were gone. Car hit speeds of 60/65 MPH for more than 3 miles on a turnpike. Parking brake did not work, brake pedal was down to the floor and I could not control the speed of the auto. After traveling more than 3 miles, in the shoulder, I put the gear into neutral and the car began to slow down and finally stop. Towed from turnpike to dealership. Know there have been problems with the 2006 model, but is there anything similar to my experience with the sonata 2009.

I have a major problem with my brakes. While driving they will suddenly go out. I have to press the pedal almost to the floor to try and stop the car. My car was repaired in september 2015, november 2015, december 2015 and my brakes went out again on yesterday, february 15, 2016 while on the highway. This is a serious problem and could end up being a deadly problem.

On july 1, 2014 the rear caliper on the driver's side of my car had seized, stripping the brakes to metal on metal. On august 30, 2014, the rear caliper on the passenger side of the car followed suit. Less than one year later I have replaced each of the rear calipers once again. I had the rear driver's side repaired on may 15, 2015, and the rear passenger side on june 9, 2015. I bought the car with just over 53,000 miles on it in 2013. Today, it has 101,000 miles on it and I have replaced four calipers, three rotors and five sets of brake pads. Each time my calipers failed I was placed in danger of total brake failure and fire, unknowingly. The mechanics who worked on my car have individually theorized that an engineering failure is the cause of this issue. Last week I contacted hyundai for financial reimbursement for the repairs. The company stated that they could not reimburse me since the parts were not replaced with hyundai factory parts, or repaired by a hyundai certified dealership. I am aware that there was a class action lawsuit against hyundai based on this issue in the state of new york. I have also read, and heard about many other people having this exact problem (rear caliper problem) in their hyundai sonatas, built between the years 2006-2010.

I had my car towed to the dealership in january after my brakes failed on the way to work. By putting the brake pedal all the way to the floor I was able to stop the car. The dealership told me it was the right rear caliper that had seized. They repaired that caliper, but I expressed my concern for the left rear caliper being damaged and was told that it was "fine." well a few months later, my left rear caliper has seized and I had it towed to the dealership. They tell me that it is no longer under warranty. I told them that this is a known issue and that I expressed my concern about the left rear caliper in january. They tell me that it is up to hyundai to decide whether it will be covered or not. This is ridiculous! Peoples' lives are at risk!

As I was driving in city traffic, I noticed a grinding noise coming from the rear as I applied the brakes. It became worse as I continued to drive and brake, so I parked the car as soon as I could. I brought it into the dealer. They said the rear brake pads were completely worn away. They said I needed new rear brake pads and rotors, because the rotors had become too damaged to use. I had the hyundai service department replace the rear brake pads and rotors. There was no indication (I.e. A typical "squeal") that would have alerted me to wear on my brake pads. They were simply gone. I have serious concerns about this incident, as brake failure could have occurred had I not stopped driving and gotten my car to the service department as soon as possible. 38,000 miles is far too early for rear brake pads to be completely worn away. I do not know of any other vehicle where the rear brake pads would have completely worn away at such low mileage. I suspect a manufacturing defect has LED to premature rear brake wear. This could have LED to a serious accident.

I brought my 2009 hyundai in for 16,500 mile check and was informed that my rear brakes failed and the brake shoes and rotor needed replacement. I told them I had not noted any symptoms of or sound of brake failure and would get a second opinion. At 18,701 miles I noticed noise while breaking and returned to the dealer the service manager suggested the damage was caused by driving with the emergency brake on. I told him that I do not ever need to use the emergency break and surely didn't drive with it on! He then said it was caused by rust. I wouldn't expect rear brakes to fail at 16,000 miles. After checking on-line I found it is a common failure with sonata. I had to pay $423.00 to repair what I consider to be a design or manufacturing defect.

Rear brake failure on a 2009 hyundai sonata. Brake slides clog with dirt or rust causing them to become inoperable. They either get stuck in the applied position which causes them to wear to the point of metal to metal causing extreme heat and possible fire or they stick open and do not engage when applied.
